If ponies think Anon is some kind of weird animal, and Fluttershy can talk to animals, can animals and Anon talk to each other?

To make the cover image, I heavily edited the MLP IDW comics panel https://derpibooru.org/images/3007495.

The Equestrian Postal Service used to be MUCH more dangerous.

"Now that we've invented paper," Princess Celestia tried to explain to her sister Luna, "we can send a message to another pony without the necessity to write the message on a THIRD pony, let alone ordering that third pony, upon pain of death, to seek out the recipient and display their flank."

When magic's slow decline dooms Equestria, ponies write letters to a future they don't expect to see.

_{This story MIGHT turn out to be an entry in the "A Thousand Words Contest," maybe?

Which of the main MLP:FiM characters would be most likely to kill somepony?

Spoiler: All of them.

Someone asked this question in "The Writers' Group," and I thought the question deserves a full answer.

Locked in a room with a vampire, Twilight Sparkle awaits her own death.

"I'm counting off the seconds until you die," the domineering redhead said coldly. "One. Two. Three. Four. Five..."

This story might or might not be an entry in the A Thousand Words Contest. (Who even knows? I don't think I'm all that good at tag targeting, and an author can only have one final entry per category.)
_{(Initial contest announcement with more details is here. It already has at least fifty or sixty entries, so at this point I'm just trying to torment Bicyclette by promoting the contest even more to help make her and her co-judges read more stories than anyone has ever had to read before!

Cadance wonders what Flurry Heart is the alicorn princess OF.

Twilight Sparkle turns perfectionist (Ha! I'll bet you never saw THAT one coming!) and tries to figure out who's more inadequate, Flurry Heart or her mother?

This is what happens when you leave your "Cadance Is a Terrible Mom" competition folder (EDIT: link to main contest page) open the night after the deadline. People show up and TRY TO PUT THINGS in it.

"Any regular old unicorn can do magic. That's nothing special." Years ago when they were fillies, that's what Twilight told Trixie.

What if Trixie had listened?

Mild Content Warning? In this story, somepony does briefly verbally suggest the possibility of serious physical injury and spurting blood if a trick goes wrong. But compared to the actual MLP:FiM show about Trixie launching herself from a cannon into a manticore's throat? Maybe it almost isn't violent ENOUGH for a Y-7 rated cartoon.

(As usual, I made the story image myself by editing MLP screencaps.)
